8. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI - Motivation Expectations of instant access Legacy materials have value  Scientific  Historical  Cultural Part of the mission of the World Data Center

9. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI – Big Picture Creating an on-line gazetteer of who has what and where Creating a searchable bibliographic database of records and literature from the three prior IPYs  These records are scattered around the world and many have never been cataloged Digitizing materials held at NSIDC and a variety of other facilities around the world based on advisory committee recommendations Allowing direct access to those materials that are or will be made available digitally (subject to usual copyright restrictions) Creating digital data sets from analog sources where appropriate

10. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO Glaciology DAHLI – On-Line Gazetteer

11. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI – Searchable Database A merger of library style and data center style interfaces

12. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI - Proposal Status NOAA Climate Database Modernization Proposal funding continues  Pays for materials digitization  Could pay for keying/OCR with QC of data sets deemed to be valuable  Negligible funding for NSIDC staff time & facilities

13. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI - Proposal Status (continued) NSF IPY DAHLI proposal is still pending  Advisory committee  On-line gazetteer  Merged digital library/data center web presence  Intercontinental backup  Staff support

14. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI – Accomplishments IPYPD agreed to extend their original plans to allow inclusion of materials from previous IPYs 53 books, technical reports, etc. have been scanned and QC’d; some materials sent back for rework Text bibliography created and posted to NSIDC DAHLI website ~1,300 IGY-related photos scanned to be added to the NOAA@NSIDC Glacier Photograph Database NSIDC holdings of IPY-related materials have been added to the IPYPD

15. R. Duerr and A. Wallace, NSIDC, GSA 2007 – Denver, CO DAHLI – Current Activities Climate Database Modernization Program  Continuing local digitization efforts  Contemplating whether to start extending program to partner holdings…
